Evidence of backcross inviability and mitochondrial DNA paternal leakage in sea turtle hybrids.

Hybridization is known to be part of many species' evolutionary history. Sea turtles have a fascinating hybridization system in which species separated by as much as 43 million years are still capable of hybridizing. Indeed, the largest nesting populations in Brazil of loggerheads (Caretta caretta) and hawksbills (Eretmochelys imbricata) have a high incidence of hybrids between these two species. A third species, olive ridleys (Lepidochelys olivacea), is also known to hybridize although at a smaller scale. Here, we used restriction site-associated DNA sequencing (RAD-Seq) markers, mitogenomes, and satellite-telemetry to investigate the patterns of hybridization and introgression in the Brazilian sea turtle population and their relationship with the migratory behaviours between feeding and nesting aggregations. We also explicitly test if the mixing of two divergent genomes in sea turtle hybrids causes mitochondrial paternal leakage. We developed a new species-specific PCR-assay capable of detecting mitochondrial DNA (mtDNA) inheritance from both parental species and performed ultra-deep sequencing to estimate the abundance of each mtDNA type. Our results show that all adult hybrids are first generation (F1) and most display a loggerhead migratory behaviour. We detected paternal leakage in F1 hybrids and different proportions of mitochondria from maternal and paternal species. Although previous studies showed no significant fitness decrease in hatchlings, our results support genetically-related hybrid breakdown possibly caused by cytonuclear incompatibility. Further research on hybrids from other populations in addition to Brazil and between different species will show if backcross inviability and mitochondrial paternal leakage is observed across sea turtle species.

Isolated cuboid dislocation: case report.

Isolated cuboid dislocation without fracture is a rare injury, and there is a lack of literature describing its treatment. Studies report the use of closed or open reduction, with Kirschner wire fixation in the treatment of these injuries. This case report presents the clinical condition of a 24-year-old male patient who arrived at the emergency department with an isolated dislocation of the right foot cuboid bone without the presence of a fracture, after suffering trauma during a football game. Open reduction was performed in the surgical center with stabilization and fixation using a Kirschner wires. The patient showed an excellent response to the treatment, with no loss of the foot's range of motion.

RANGE OF MOTION AFTER BONE BLOCK PROCEDURES FOR SHOULDER INSTABILITY: SYSTEMATIC REVIEW.

Objective: to determine the surgical indications for glenoid bone grafting associated with better postoperative ranges of motion. Methods: This systematic review was conducted according to PRISMA. The included studies were subdivided according to the criteria used to indicate glenoid bone graft surgery: group for radiological indications only (Group R), group for radiological indications associated with clinical indications (Group R + C), and group for arthroscopic indications (Group A). The extracted and evaluated data were the range of motion of the shoulder. Results: in the electronic search conducted in October 2022, 1567 articles were selected. After applying the inclusion criteria, 14 articles were selected for the systematic review. Regarding the ranges of motion, group A had the highest number of statistically positive results together with group R. Group A showed positive results in elevation parameters, loss of lateral rotation in adduction, and medial rotation in abduction. Group R showed positive results in lateral rotation in adduction and loss of lateral rotation in adduction. On the other hand, Group R + C was the one that presented the highest number of statistically negative results, in the following parameters: elevation, lateral rotation in abduction, loss of lateral rotation in adduction, and medial rotation in abduction. Conclusion: the subgroups presented variable results in the evaluated parameters; however, the groups with arthroscopic and radiological indications showed the highest number of positive results, with the latter group showing the best results regarding lateral rotation.

Shoulder injuries in Brazilian professional football players: epidemiological analysis of 3828 games.

OBJECTIVES: Football is a globally played sport that poses potential risks for musculoskeletal injuries. Upper-limb injuries have a lower incidence rate than lower-limb injuries but can still cause absenteeism and performance impairment in football players. This descriptive epidemiological study aimed to evaluate and compare the epidemiological data on shoulder injuries among professional football players in two major Brazilian football championships. METHODS: Data were collected throughout the championships, and club physicians medically evaluated each player during official games using two online forms. The collected information included the player's age and position, injury diagnosis, laterality, location on the field where the injury occurred, playing time, imaging examinations performed, need for surgical treatment, time to return to play (TRP), and recurrence of the injury. The incidence of injuries was evaluated using the Federation Internationale de Football Association (FIFA) incidence formula. RESULTS: A total of 107 shoulder injuries were recorded (4.3% of all injuries), with a FIFA incidence of 0.847. Glenohumeral dislocations (GHDs) and acromioclavicular dislocations (ACDs) accounted for 37.38% and 35.51% of all shoulder injuries, respectively. Goalkeepers and defenders presented, respectively, a 2.15 and 1.57 times increased risk of suffering shoulder injuries, while attackers presented a 0.63 times decreased risk. Injury recurrence was observed in 14.95% of cases, with GHDs and ACDs showing recurrence rates of 35.00% and 5.26%, respectively. Surgery was performed in 9.35% of cases, with GHDs representing 50% of all surgeries. The average TRP was 22.37 days, with severe and major injuries accounting for 11.21% and 10.28% of all injuries, respectively. Goalkeepers had the highest average TRP of 36.15 days. Recurring injuries had a higher average TRP of 33.44 days compared to nonrecurring injuries, which had an average TRP of 20.43 days. Surgically treated injuries had the highest average TRP of 112.5 days. CONCLUSION: Shoulder injuries in the professional football scenario are of great concern due to the high recurrence rate and need for surgical treatment, which will lead to a long TRP. These findings emphasize the need to implement prevention protocols and effective treatments to reduce the consequences of such injuries, which are usually underestimated in this sport. LEVEL OF EVIDENCE: III.

Anabolic steroids and the evaluation of patients with acute PM tendon rupture using microscopy and MRI.

This study presented a pioneering investigation of the changes in the magnetic resonance imaging images of pectoralis major muscle (PMM) tendon rupture. In all, 26 men were evaluated with acute total PMM rupture (<3 months since injury) with a mean age of 37.3 years (SD = 9.7 years) and 10 control patients with a mean age of 32.6 years (SD = 4.2 years). The evaluation of the tendon PMM injuries was based on the magnetic resonance imaging exam and the histological analysis. The magnetic resonance imaging of the surgically showed two (7.1%) contralateral sides were normal, 16 (57.1%) showed superior tendinopathy, and 10 (35.7%) had total tendinopathy. Inferior tendinopathy was not observed. The tendon histology revealed degenerative changes in 16 (66.7%) fragments, with 12 (50.0%) considered as mild (<25%), and four considered as (16.7%) high (>50.0%) tendinopathy. Total acute rupture of the PMM tendon among weightlifters might be associated with tendinous degeneration prior to injury.

Distal rupture of the biceps brachii tendon in a female mixed martial arts athlete: a case report.

The distal rupture of the biceps brachii muscle tendon (DBT) accounts for 3% of biceps ruptures. Diagnosis typically relies on high clinical suspicion and complementary imaging studies, with >90% of cases documented in males between the fourth and sixth decades of life. Reports of DBT ruptures in females are scarce, mostly involving partial and degenerative injuries. Here, we present an unprecedented case of a 28-year-old female professional mixed martial arts athlete with a total traumatic DBT rupture. The athlete underwent surgical repair using anchor reattachment technique. No complications were observed, and the athlete showed satisfactory outcomes, being cleared for physiotherapy after 2 weeks and returning to sports after a 3-month postoperative period.

Surgical treatment of traumatic rupture of the teres major tendon in a professional gymnast: a case report.

Teres major injuries are rare and are generally treated conservatively, except in high-performance athletes. This report describes a case of traumatic rupture of the teres major at its myotendinous junction in a professional gymnast. The patient underwent surgical treatment 10 days after the injury. Six months post-surgery, the patient achieved complete recovery of the range of motion and strength, returning to the pre-injury performance level, guided by physiotherapy rehabilitation. This is the first documented case in the literature of surgical treatment of this injury in a professional gymnast. The main lesson from this case is that early surgical repair in elite athletes can result in excellent functional outcomes and allow return to sport at the pre-injury performance level.

ASSESSMENT OF THE LEVEL OF SATISFACTION OF PATIENTS SUBMITTED TO LATARJET SURGERY UNDER OUTFIT SYSTEM COMPARED TO HOSPITAL SYSTEM.

Anterior shoulder instability causes functional changes that affect patients' quality of life. The Latarjet procedure is one of the most frequently performed surgeries for cases of recurrent shoulder instability. Objective: To assess the level of satisfaction of patients who underwent the Latarjet procedure in outpatient settings (day hospital) compared with inpatient settings. Methods: A questionnaire was administered to both groups and a descriptive analysis of the results was performed. Results: 51 patients were included, with a mean age of 29.9 years, 82.3% men and 17.6% women. Of the patients who underwent surgery in the day hospital, 46.1% were operated within 100 days of their first outpatient visit; among those in the inpatient group, 76.3% underwent surgery more than 200 days later. Delays occurred in 15.3% of cases in the day hospital compared with 68.4% in the inpatient group. Of the patients in the day hospital, 92.3% felt comfortable contacting the medical team in case of complications and would perform the procedure again in the same setting. Moreover, 63.2% of inpatients would have preferred to have been discharged on the same day. The final satisfaction rate for both groups was 100%. Conclusion: Outpatient surgery guarantees more patient comfort, safety, and can be performed in a timely manner and with fewer delays, which has influenced patients' decision to have surgery during the COVID-19 pandemic.

Bristow-Latarjet Surgery: A Current Overview in Brazil.

Objective To provide a current overview of the Bristow-Latarjet surgery in Brazil. Materials and Methods This cross-sectional study was based on an electronic questionnaire with 26 items, which was sent to active members of the Brazilian Society of Shoulder and Elbow Surgery (Sociedade Brasileira de Cirurgia do Ombro e Cotovelo, SBCOC, in Portuguese). The questionnaire addressed training, surgical technique, complications, and postoperative management. Results We sent the questionnaire to 845 specialists from April 20 to May 12, 2021, and 310 of them answered i in full. During their specialization, most specialists participated in up to ten Bristow-Latarjet procedures. The most frequent complication was graft fracture, while the most common technical difficulty was screw positioning. In total, 50.6% and 73.9% reported having experienced intraoperative and postoperative complications respectively; 57.1% declared performing subscapularis suture; 99.7% indicated postoperative immobilization; and 61.9% considered graft consolidation fundamental. Conclusion Most specialists participated in up to ten Bristow-Latarjet procedures during the specialization, but 13.5% of them graduated without participating in the surgery. The most frequent complication was graft fracture. The most common technical difficulty was screw positioning. Most participants prefer postoperative immobilization since they believe graft consolidation is essential to resume the practiced of sports. The highest complication rate occurred with specialists who have obtained their titles 11 to 15 years ago. In Brazil, the Southeast region is the largest producer of specialists and has the highest concentration of these professionals.

Glenoid Bone Loss - A Retrospective Evaluation of Functional Outcomes after Bone Block Surgery for Anterior Shoulder Instability in High-demand Athletes.

Objective This study assesses the relationship between the glenoid bone loss size and range of motion, functional outcomes, and complications in high-performance athletes undergoing bone block surgery for anterior shoulder instability. Methods This retrospective study evaluated postoperative outcomes in athletes submitted to bone block surgery for anterior shoulder instability. In 5 years, 41 shoulders underwent the procedure; 20 had bone losses up to 15%, and 21 shoulders presented bone losses ranging from 15% and 25%. Results There was no statistically significant difference regarding postoperative complications, new dislocations, and the rate of return to sports. In addition, the quantitative criteria evaluated, i.e., ranges of motion and functional scores, showed no statistically significant difference between groups. Conclusion The size of the bone loss per se does not seem to affect functional outcomes and complications from these procedures, which are safe techniques for small and large bone losses.

Rupture of the bilateral and simultaneous tendon of the pectoralis major muscle. Description of three cases.

Pectoralis major muscle tendon ruptures associated with physical activity or effort are no longer uncommon in the medical literature. Treatment has also evolved significantly in the last 20 years. However, simultaneous bilateral rupture has only been described in a few cases. This article reports three cases with simultaneous bilateral rupture and describes the examinations and treatment performed. Bilateral lesions, although infrequent, also require early diagnosis and treatment in the acute phase. The chronic phase requires tendon grafting for full correction and a slow rehabilitation process.

RESULT OF BONE BLOCKING SURGERY IN COMBAT ATHLETES WITH ANTERIOR SHOULDER INSTABILITY: A PROSPECTIVE STUDY.

Objective: This study aims to understand the way fighting athletes respond to bone block surgery in the treatment for shoulder instability. Methods: Prospective clinical study with competitive fighters with shoulder instability who underwent bone block surgery from 2013 to 2016, followed by a postoperative rehabilitation protocol. For the evaluation, eight combat athletes with anterior shoulder instability were treated, with a total of nine shoulders, since one athlete underwent bilateral surgery. All patients signed the Free and Informed Consent Form. The evaluation protocol included medical consultation, radiography of the operated shoulder, degree of active and passive lateral rotation; degree of active and passive elevation; visual analogue scale (VAS) for pain; Athletic Shoulder Outcome Rating Scale (EROE; acronym in Portuguese) scores; Western Ontario Shoulder Instability Index (WOSI), and American Shoulder and Elbow Surgeons (ASES). Results: We observed a decrease in the range of passive and active movement in the recent postoperative period. In later postoperative, values were close to those in the preoperative period at the end of the follow-up. There was improvement in pain, and in all ASES, WOSI and EROE scores no complications were documented. As for returning to sport, two athletes did not return, one of them due to shoulder pain and the other due to retirement. Conclusion: Bone block surgery has shown good functional results in uncomplicated combat athletes. Level of Evidence IV, Prospective Case Series.

Protocol for the Request of Knee Magnetic Resonance Imaging in Elderly Patients with Suspected Osteoarthritis: Reduction in Test Requests and Impact on Management and Diagnosis.

Objective To develop an evidence-based protocol to guide magnetic resonance imaging (MRI) requests in elderly patients with suspected knee osteoarthrosis and to evaluate its effectiveness after implementation. Methods The institutional protocol was developed after reviewing the literature during the first semester of 2018. The control group was defined as patients cared for in the first semester of 2018, before the implementation/dissemination of the institutional protocol, and the study group was composed by patients cared for during the second semester of 2018 after the standardization of MRI requests for suspected knee osteoarthrosis. Results Our sample included 826 patients undergoing knee MRI, with a mean age of 69.3 years. Protocol implementation decreased MRI requests and increased radiograph requests ( p < 0.001). After the implementation of the protocol, the MRI changed the diagnosis or treatment in only 11.2% of the cases. Conclusion Protocol implementation resulted in a 47.5% reduction in the number of requests for knee MRI, with most (89%) patients with alteration in diagnosis or treatment. Level of evidence: case-control study (IIIB).

HYLAN G-F 20 VERSUS TRIAMCINOLONE IN THE TREATMENT OF PRIMARY SHOULDER OSTEOARTHRITIS. RANDOMIZED TRIAL.

Introduction: The aim of this study was to evaluate the effect of using an intra-articular injection of hylan G-F 20 (HA group) on primary shoulder osteoarthritis compared with an intra-articular triamcinolone injection (T group). Materials and Methods: The patients were randomized into 2 groups: in the HA group a single dose of intra-articular hylan G-F 20 was administered and in the T control group a dose of triamcinolone 20 mg was administered. The participants were evaluated at 1 week, 1, 3, and 6 months after the procedure. The patients were evaluated for pain, range of motion, Constant score, modified UCLA score, and SPADI. Results: Seventy patients met the inclusion criteria and were randomized to the HA (38) and T (32) groups. Improvements in range of motion were significant (p > 0.05). We observed decreases in the general visual analog scale (VAS) for pain in both groups, especially in the cases of mild and moderate arthritis that received hyaluronic acid (mean values from 8.1 initially to 4.9 after 6 months) (p = 0). Conclusions: Both injections led to a decrease in pain and an increase in patient satisfaction. The results tend to be better and longer lasting in patients receiving hyaluronic acid. Level of evidence II b; Cohort study.

ORTHOPAEDIC TELEMEDICINE SERVICES DURING THE CURRENT NOVEL CORONAVIRUS PANDEMIC.

Introduction: To evaluate the use of telemedicine by physicians specializing in orthopaedics and traumatology at the authors' institution, and to assess the rates of satisfaction and resolution for this type of care. The current global coronavirus disease 2019 (COVID-19) pandemic has resulted in the expansion of telemedicine services. However, quality measures and barriers for physicians dealing with the rapid increase in patients have not been well described. Materials and Methods: This study included 255 patients with orthopaedic complaints. Between 24 and 48 hours after the appointment, independent physicians, who did not participate in the initial appointment, contacted one another to assess the degree of satisfaction with the appointment, and whether there was a solution to the orthopaedic complaint. Results: There was a need for referral for face-to-face consultation in only 13.8% of cases. When asked about the probability of recommending telemedicine to a friend/family member, the answer was 90.3%. The satisfaction rate with the service was 91.1% and 93.69% of patients would return for a telemedicine consultation. Telemedicine consultations solved the problem in 82.74% of cases. Conclusions: Telemedicine care in orthopaedics proved to be a service modality with a high rate of satisfaction among the patients evaluated. Level of evidence III, Retrospective cohort study.

Isokinetic Evaluation of the Shoulder After Bristow/Latarjet Surgical Procedure in Athletes.

Objectives To evaluate the muscular strength of the internal (IR) and external (ER) rotators of the shoulder after Bristow/Latarjet surgery. Methods Cross-sectional study with 18 patients (36 shoulders). The isokinetic evaluation was performed using the Biodex 3 System Pro dynamometer (Biodex Medical System, Inc., Shirley, NY, USA). The athletic shoulder outcome rating scale (ASORS) and the visual analogue scale (VAS) were applied. Results The values of peak torque and maximum work in concentric and eccentric mode on the non-operated shoulder were higher than on the operated side for both the IR and ER ( p < 0.01). The conventional and functional balance between the ER and IR showed no differences between the operated and the non-operated side. When comparing patients with postoperative time < 1 year or 1 year, no differences were observed in peak torque values at 60°/s and 240°/s and maximum work at 60°/s and 240°/s of the IR to the operated shoulder. However, the peak torque values of 60°/s and 240°/s and maximum work at 60°/s and 240°/s of the ER were higher in subjects with postoperative time ≥ 1 year in all variables ( p < 0.05). Conclusions There was a decrease in the strength of the IR and ER in the operated shoulder compared with the healthy shoulder. However, the conventional and functional balance was maintained.

Evaluation of Latarjet procedure in female athletes: a 3-year follow-up prospective cohort study.

Background: Although there is a low incidence of shoulder instability in women, this population is still representative and is often associated with lower rates of return to sports. Few studies have evaluated the results of the Latarjet procedure in this population. Methods: This was a prospective cohort study of female athletes who underwent the Latarjet procedure between 2013 and 2018. The participants were followed up for 3 years. The primary outcomes of the study included the visual analog scale for pain; range of motion: active elevation, passive elevation, active external rotation, and passive external rotation. The functional scores were as follows: American Shoulder and Elbow Surgeons score, the Western Ontario Shoulder Instability Index, and the Athletic Shoulder Outcome Rating Scale. Additional data were collected regarding return to sport, complication rates, and patient satisfaction. Results: Thirteen female athletes who practice Soccer, Volleyball, Basketball, Handball, Judo, or Weight training were evaluated. There was a significant reduction in the mean range of motion for all movements at 4 weeks after surgery. Patients recovered a range of motion similar to the preoperative values after 6 months. The mean visual analog scale reached 6.39 at the first week after surgery and decreased to values below preop at 8 weeks. The mean preoperative Western Ontario Shoulder Instability Index was 126.77 (min 118; max 135), and at the end of follow-up, the WOSI index was 45.08 (min 37; max 65; P < .05). The mean preoperative American Shoulder and Elbow Surgeons score was 41.61 (min 35; max 46), and at the end of follow-up, the mean ASES score was 84.46 (min 80; max 90; P < .05). The mean Athletic Shoulder Outcome Rating Scale in the preoperative period was 39.38 (min 37; max 42), and at the end of follow-up, the mean ASORS score was 83.15 (min 77; max 85; P < .05). The rate of return to sports was 92.3%, and 84.6% of patients were satisfied with the surgery. The aesthetic satisfaction rate was 76.9%. The complication rate was 15.4% (1 screw failure and 1 dislocation recurrence). Conclusion: Latarjet surgery in female athletes showed high rates of return to sports and improved functional scores without impairing range of motion after the procedure. Recurrence and complication rates were low. In addition, treatment was associated with improved functionality and patient satisfaction.

Epidemiology of Upper Limb Injuries in two major Brazilian Soccer Championships from 2016 to 2019.

PURPOSE: To evaluate epidemiological data of upper limb injuries in professional athletes who participated in two major Brazilian soccer championships between 2016 and 2019. METHODS: A prospective cohort study was conducted to evaluate the teams of two divisions over four seasons within the Brazilian Soccer Championship and the Paulista Soccer Championship. Clubs and their doctors were contacted to participate in the study and guided on the correct way to enter data via online platforms: Transfermarkt (Transfermarkt GmbH & Co. KG) and Survey Monkey (Momentive.AI). Demographic data, injury characteristics, and FIFA Incidence Formula were analyzed. RESULTS: Overall, the study analyzed 3,828 matches and 126,357 hours of play. Upper limb injuries were registered 169 times, representing 6.8% of total injuries, with a FIFA incidence of 1.34. Most lesions occurred in forward players (21.3%), the shoulder exhibited the highest number of injuries (63.3%). The player's position was related to the location on the field where the injury occurred (p < 0.001); however, there was no relationship between the type of injury and the location on the body (p > 0.001). The average time to return to play was 19.1 days (range 0-200 days) and it was longer for goalkeepers. The necessity of surgical treatment was statistically associated with additional time to return to play (p < 0.001). CONCLUSIONS: Shoulder injuries were the most frequent upper limb injury sustained during the two major Brazilian soccer championships. Forward players suffered the most upper limb injuries and goalkeepers experienced the longest time to return to play.
